I wouldn't take it as a good sign if she's told you not to speak to her. Although thats not fair encouraging you to like her if she has a bf and has no intention of getting with you.
What about beinf friends with a girl? I mean, if you've messed up royally, and she asks you to be friends for the meantime and let her get to know you again... won't you just slip into friendship mode?
Aspies women, I've no idea.
There aren't that many out there like this, but you might try to look for someone who doesn't care about being social, like someone who seems like a misfit or is awkward around social situations or who doesn't fit in and see if you can be friends first.
^Sounds like an Aspie 
I personally would love to meet a nice Aspie guy. I don't know, but dating an NT guy just seems sort of...daunting. Never been in a relationship before, never felt the need to, but the last week or so...never thought I'd say this but I've felt sort of lonely.
I guess since middle school I've sort of avoided relationships because I never know when someone was being serious about asking, or if they were just teasing. Like this one guy in middle school, I remember, he kept asking me every day, and I always said no, and I just never knew if he really meant he wanted to get involved or if he was just trying to be excessively annoying. And then those times when a group of guys is together, and one comes up to you, points to one of the other guys and says "Hey, he likes you"...hat the hell is that supposed to mean?
I've always assumed it was joking/screwing around. I roll my eyes and walk off.
I've come to the realization as of late that I wouldn't know if a guy was flirting with me unless I was told so, and even then I'd find it hard to believe. So many times when I'm out with my mom she'll say "Hey, he's checking you out" or something along those lines. Then at work today, we got to talking about dating and relationships, and one of my co-workers said "Well Shannon's the only single one, and she's not dating right now...are you?" and i was just thinking "Well, no, but it's not that I just am not interested, it's that I have no idea what to do" but I just ended up nodding. Then we were talking about someone else's relationship and my boss turned to me and said "God, I know why you're not dating, this *** is confusing!" and I said "Yep."
I just don't get that kind of stuff.
Are you renouncing it too them EM? I don't blame you.
Although I do have Michelle Rodriguez handcuffed to my bed for when I fall off the wagon

Always have a back up plan

fall off the wagon and into.................................ahem
Especially my daughter who is calm and co-operative all day in class. Then when she comes home goes into almost complete meltdown. Then onto her obsession (computer codes)
I suspect it takes all her energy to get through the day without showing any signs of aspies. then must have time out.
